Background and objectives: Thyroid disorders (TD) are common among patients with type 2 diabetes mellitus (T2DM). Information on types of functional and structural TDs among Bangladeshi patients with T2DM is scarce in the literature. The present study aimed to determine the magnitude and characteristics of different TDs among Bangladeshi diabetic patients attending an urban healthcare center in Dhaka. Material and methods: The study included patients with T2DM who attended an urban Endocrinology Outpatient consultation center in Dhaka over a period of two years. Diagnosis of TDs was based either on previous medical records or on investigational results of thyroid functions/gland during the first visit. Standard criteria were used to diagnose TDs. Results: Total 1424 patients with T2DM were enrolled in the study. The mean age of the study population was 48.8 ± 12.9 years and 45.2% and 54.8% were male and female respectively. Among 1424 participants 217 (15.2%) had functional and/or structural abnormalities of thyroid gland. For those with abnormal thyroid function (14.3%), the most common was clinical hypothyroidism (10.5%), followed by subclinical hypothyroidism (2.6%), and clinical thyrotoxicosis (1.3%). Except for one, all patients with overt hypothyroidism had primary hypothyroidism. Among patients with overt thyrotoxicosis, Graves’ disease was the most common entity (50%). Multinodular goiter was the most frequent diagnosis among structural abnormalities (7 out of 13). Female sex (OR: 3.0, 95%CI: 1.5, 6.1, p=0.003) and obesity (OR: 2.3, 95%CI: 1.1, 5.0, p=0.039) had higher odds of having a diagnosis of overt hypothyroidism among patients with T2DM. Hypertension, dyslipidemia and obesity were significantly (p < 0.05) higher in diabetic patients with overt hypothyroidism. Conclusion: TDs especially hypothyroidism are common among female Bangladeshi patients with T2DM. Dyslipidemia and obesity are significantly more in overt hypothyroidism among patients with T2DM.
